Ciena 130-0241-900 Multiwave/Metro/CoreDirector/CN4200 DWDM transmission Optical Transmission Module

The Ciena 130-0241-900 is a 980nm pump module for the Ciena MultiWave DWDM platform. A pump module supplies the high-power 980nm (or, on other variants, 1480nm) laser light that energises an Erbium-Doped Fibre Amplifier’s (EDFA) doped fibre, which is what lets an EDFA boost a multiplexed optical signal across all its wavelength channels at once without converting it back to an electrical signal first. It is common equipment shared across the shelf’s amplifier stage rather than a per-channel card. Genuine spares of this kind are needed when an amplifier’s optical output degrades or fails, since a weak pump directly reduces the amplifier’s gain and reach. Confirm the exact pump configuration and amplifier variant fitted to your shelf before ordering.
